I am finding that sometimes when I turn on the reader and then try to read the book I last had open I get a message saying "This content is protected by DRM". It's happened on a couple of books paid for but not from any of the freebies from Gutenberg project (- now if that's not the lolly shop, what is?!) If I then open something else and go back to it, it stops happening, but loses my place. I have also tried putting in a book mark but this also seems to get wipes.
